Axle bearings with fully annular axle brasses, which are carried in ahollow cylindrical aperture in the axle box have hitherto been securedwith the axle box by a screw which penetrated the axle box and enteredinto a hole in the fully annular brass. This arrangement is unreliableand disadvantageous because, as is well-known, a screw does not form atight joint. Therefore oil escapes particularly from axle bearings withcirculating and cooling lubrication, although the maintenance of thisamount of lubricant is absolutely necessary in order to ensure that thesupply member dips to a certain depth into the lubricant Well. Thepresent invention sets the problem of constituting the securing means ofthe fully annular brass without breaking through the axle box in anyway. The problem is solved according to the invention, by arranging, onboth sides on the undivided fully annular brass or on the undividedshell which holds the divided fully annular brass together, stops whichabut against the end faces of the hollow cylindrical part of the axlebox and connect the fully annular brass with the axle box. Preferablythe stops are formed as threaded rings.

The drawings show constructional forms of the inventive idea by way ofexample.

Figure l is a longitudinal section through an axle bearing, according tothe invention, with a two-part fully annular brass and sleeve holdingboth parts together while Figure 2 shows in the same longitudinalsection an axle bearing having a single undivided fully annular brass.

I indicates the upper, 2 the lower half of the fully annular brass whichsurrounds the journal 3 and, according to the problem of the presentinvention, is to be xed to the axlle box 4 or its hollow cylindricalaperture 5 so that the fixing means necessitate no breaking through theaxle box. To this end there are arranged on the onepiece steel shell 6,which holds together the two halves I and 2 of the brass, both towardsthe collar 'I of the` journal as well as towards the enlarged part 8,threaded rings 9 and Il] which in the xed position abut with their frontfaces against the brasses I and 2 and against the front faces of theaperture 5, and in this way prevent axial displacement of the fullyannular brass relatively to the axle box. Rotation of the axle brassrelatively to the axle box is prevented in the usual manner bytangential keys or by other equivalent means.

The assembly and disassembly of the new fastening device takes place asfollows:-

First the two halves of the brass, with the axle box removed, are fittedon the journal and held in position by the steel sleeve 6. The screwring Ill had already been previously inserted on the enlarged part 8.After iitting the brasses and the sleeve 6 the screw ring I is screwedon the 5 steel sleeve 6 and secured. After this the axle box is fittedon the journal by introducing the sleeve 6 into the hollow space 5 ofthe axle box 4. As soon as the axle box is iitted, the screw ring 9 isscrewed on and secured. After this the del0 vices I I and I2 areconnected to the journal collar I and the device I3 to the axle box 4,so that the lubrication of the axle bearing is ensured by way of thelubricating grooves I4. Finally the cover I5 is screwed on. Theprocedure takes place obl5 Viously in reverse manner on disassemblingthe axle brasses.

Figure 2 shows in longitudinal section an axle bearing with a single,undivided fully annular brass I6 which is secured against displacements20 by threaded rings 9 and I0 arranged at the side of the collar andenlarged part. In order to be able to place the bearing brass on theaxle journal, the axle journal collar 'I is detachably mounted.Moreover, the construction of the axle bearing according'to Figure 2corresponds exactly to the construction af the axle bearing according toFigure 1 so that the reference numerals are the same. The insertion andremoval of the bearing brass are also effected accordingly.

I claim:-

1. An axle bearing comprising in combination a one-piece axle boxhousing having a hollow cylindrical aperture, an axle journal includinga collar and an enlarged part, a multi-part axle box arranged betweenthe collar and the enlarged part, a one-piece annular cylindrical sleeveon the said multi-part axle box for holding the parts of the axle boxtogether, the said axle box and the said sleeve being carried in thehollow cylindrical aperture of the housing, annular stops on said sleevewhich are arranged at the side of the collar and the enlarged part andbear against the end faces of the housing part which forms the hollowcylindrical aperture.

2. An axle bearing comprising in combination a one-piece axle boxhousing having a hollow cylindrical aperture, an axle journal collar andan enlarged part, an annular closed axle box which is cylindrical on itsoutside and arranged on the axle journal between collar and enlargedpart, the said axle box being carried in the hollow cylindrical apertureof the housing, annular insertable and removable stops arranged at theside of the collar and enlarged part on the said axle box, the saidannular stops bearing against the cylindrical end faces of the housingpart which forms the hollow cylindrical aperture.

3. An axle bearing according to claim 2, the said stops being designedas a Closed threaded ring and adapted to be screwed on the annular box,the said threaded ring having an inwardly projecting annular flange andthe said flange bearing rmly against the end faces of the an- 10 nularbox in the end position.

4. An axle bearing according to claim 1, the said stops being designedas closed threaded rings and adapted to be screwed 0n the one-pieceannular cylindrical sleeve holding the parts of the axle box together,the said threaded ring having an inwardly projecting annular ange, thesaid flange bearing rmly against the end faces of the sleeve and thedivided axle box in the end position.
